W3C::LogValidator is the main module for the W3C Log Validator,
a combination of Web Server log analysis and statistics tool and Web Content quality checker.

The W3C::LogValidator can batch-process a number of documents through a number of quality focus checks,
such as HTML or CSS validation,
or checking for broken links.
It can take a number of different inputs,
ranging from a simple list of URIs to log files from various Web servers.
And since it orders the result depending on the number of times a document appears in the file or logs,
it is,
in practice,
a useful way to spot the most popular documents that need work.

the perl script logprocess.pl,
bundled in the W3C::LogValidator distribution,
is a simple way to use the features of W3C::LogValidator.
Developers can also use W3C::LogValidator can be used as a perl module to build applications.

Several articles have been written within the W3C Quality Assurance Interest Group on the topic of improving the quality of Web sites, notably by using a step-by-step approach and relying upon the Log Validator to help find the areas to fix in priority.
